摘要： In one aspect, optoelectronic devices are described herein. In some implementations, an optoelectronic device comprises a photovoltaic cell. The photovoltaic cell comprises a space-charge region, a quasi-neutral region, and a low bandgap absorber region (LBAR) layer or an improved transport (IT) layer at least partially positioned in the quasi-neutral region of the cell.

摘要： A method of fabricating a heterostructure includes providing a substrate, and implementing a non-sputtered, epitaxial growth procedure at a growth temperature to form a wurtzite structure supported by the substrate. The wurtzite structure includes an alloy of a III-nitride material. The non-sputtered, epitaxial growth procedure is configured to incorporate a group IIIB element into the alloy of the III-nitride material. The growth temperature is at a level such that the wurtzite structure exhibits a breakdown field strength greater than a ferroelectric coercive field strength of the wurtzite structure.
